  • Sahar Bagheri asked a question:
    How does the right porosity and structure soil properties for agriculture affect compressibility, plasticity and cohesion in mud-brick soil?
    ...
  • How to detect naringenin, dihydrokaempferol, dihydroquercetin, and dihydromyricetin in plant tissues? What is the CAS number of the standard?
    I read a lot of literature, but my chemistry knowledge is not enough. The standard has the same structure but a different name, so I don't know how to distinguish them.
    Gloria Ivonne Hernández Bolio · Centro de Investigación Científica de Yucatán
    I recommend you the detection bay means of HPLC and the use of standards. Also you can find attached a very useful article about the extraction and identification of glycosilated flavonoids in plant material.

    What is this disease in maize?
    Founded in between 30-45 days of the crop, with bad smell, in rainy season.
    Johan Vaerenbergh · Institute for Agricultural and Fisheries Research
    Most likely, this is Dickeya zeae (formerly known as Erwinia chrysanthemi). Occurred once in Belgium. Isolate the strain by dilution plating on any common medium and identify it by PCR and sequencing.

  • Matty Demont added an answer:
    Have you come across any African government led-initiatives that promote agricultural value chains?
    (1) Have you come across any African government led-initiatives that promote agricultural value chains; (2) Countries that are well integrated into Africa's agricultural industry?
    Matty Demont · International Rice Research Institute
    In the case of rice, this would mean for example Asian rice exporters who export rice to Africa, right? I do not see many attempts for integration. Exporters are quite integrated domestically, i.e. they govern domestic value chains in order to source a reliable supply of a certain quality of rice, but I have never really seen any attempts to integrate with African rice value chains. Instead, what is happening is that African importers are now increasingly interested in integrating with their domestic rice value chains in order to better secure their end-markets, i.e. big urban African cities, in an increasingly unstable international market. The best example is SPCRS in Senegal described in the article referenced below, a joint venture of 14 importers, processors and farmers. However, the business model is not very successful so far due to conflicts of interest and the organization of the model. Hence, I would not describe the rice export-import relations with Africa as being "integrated" in any sense. It is an adversarial relationship between exporters, brokers (often based in Geneva, Switzerland) and importers, all more or less speculating on the international market (check the French documentary "Main basse sur le riz" if interested). I hope this makes sense.
  • Matty Demont added an answer:
    Need to know about journals of Social Science (Ag. Economics) which have a high impact factor by Thompson-Reuters and do not charge any money for publishing.
    There are many journals in the field of agricultural economics, which are rated highly but they also charge money to publish the research. I am in search of some journals which do not charge money, yet they are rated highly by Thmpson-Reuters, any answers?

  • Bernhard Meier zu Biesen added an answer:
    Is there hope for African agriculture?
    African farmers hitherto cultivated their crops and reared their livestock/animals without chemicals. Then, they were introduced to the so called improved farming methods with emphasis on heavy reliance on agro-chemicals, particularly inorganic fertilizers. Years after, they are asked to go back to the traditional farming methods they abandoned, this time with new names such as "organic farming", "conservation agriculture", etc. The African farmer is now in dilemma. The future of African agriculture is bleak unless this dilemma is resolved. The question is, how can the dilemma be resolved? Better still, what is the way forward for African agriculture?
    Bernhard Meier zu Biesen · NROs, ACSAD Arab Ligue; ARI Tanzania; Agric. Investm.Ltd.
    From the time when the Roman Empire exploited and degraded lastingly much of northern Africa’s lands as granary, the continent has undergone numerous and very diverse agricultural influences and impacts, from cotton-companies to colonialists, from missionaries to commercial farmers, from Nyereres to Idi-Amins. The overall situation thus is extremely multifarious and not describable by simple short words. In 40 years of work in development cooperation I have become and remained an optimist reg. the continent’s agro-eco-system and its potential. Right now the rich & the beauty in the luxury-hotels of the Arabian Golf-Area are digesting best fruits & vegetables from small commercial farms around Addis-Abeba. The booming economies (some 10) in Africa are partly built on a flourishing agriculture with food-security for the majority of the population and attractive prices for farm-products. At the same time the Orthodox Church in Ethiopia stipulates some 100 religious holidays --- in addition to 52 Sundays --- on which farmers are not allowed to work on the fields….thus making the religious “power” in review responsible for millions of famine-victims of the past decades. Just one example of the man-made (!!) backlog in the agro-system of Africa. But the future of it is bright based on the ample experience gained and on the sober facts and potentials available. In Ruanda some 200,000 ha of swamp-lands are available for 2 harvests / year with each 6 t/ha. On some 6,000 ha this is being practiced right now. A million of additional wetlands are available on the continent for rice-cropping. Conventional agro-chemistry based production-systems parallel to biological systems are being run, tested, are competing and it is clear, that only those approaches can survive, which respect and protect the agro-ecological base and rules. There have to be strong guidelines for new and international agro-investors on the African continent in respect to social, ecological and agronomical minimum standards. So the way forward is to be based on --- among others --- : ●GAP, ●attractive prices for farm-products, ●functional rural roads and other infrastructures ●researchers who work in farmers’ fields, ---not so much in laboratories & libraries-- ●non-ideological agric. policies, ●awareness about the gigantic potentials due to 365-days vegetation-period where water is available, ●drip-irrigation with solar-pumps along all rivers, ●market-economy with social framing; ● 78% nitrogen (fertilizer) in the air over the continent, which can be made available free-of-charge by biological agriculture (rhizobium-bacteria in legumes); ●rain-harvesting with contour-oriented land-use-planning and land-scape-design; ●clever, bright, smart farmers & agronomists & politicians & investors!!!
  • Adriano Altissimo added an answer:
    Can anyone recommend a good software for analyzing a digital image for plant coverage?
    Every two weeks I have taken photos of plant species withing a known area that I am testing for change in coverage. I have been using Photoshop to determine the actual plant area coverage. However many times some of the vegetation is covered with soil due to large fluctuations of water levels causing soil to settle on leaves. This makes it really hard to use color to delineate between soil and plant. Has anyone run into this issue and have any potential solutions?
    Adriano Altissimo · Landlab
    Hi, yes, of course. We do use specific softwares able to detect green pixel, ground pixel, yellow pixels: WIN FOLIA (or WIN CAM) produced by Regent instruments - Canada- . For better results we use a closed box, with artificlal and constant light. The output is a a kind of LGC = Living Ground Cover.

  • Aini Sanusi added an answer:
    How to rehabilitate the peat swamp after it was used for plantation?
    We know that more than a thousand hectares of peat swamp in Indonesia were used for plantation, such as oil palm. In oil palm, the production will decrease after 25 or 30 years. After that, they will replant with rubber plant, but, I don't think that rubber plant should be suitable on peat swamp. If we want to rehabilitate the peat swamp, is there any ideas to rehabilitate it?

    Thank you so much for the information :)
  • Do the goals of agricultural research in sub-Saharan Africa meet the needs of growers?
    In many countries weed control, soil fertility and the lack of effective water management (both drought and flooding) are the most important impediments to farming. Unfortunately, relatively very few agricultural research programs address these issues. Do we need to re-focus our research priorities, in order to achieve higher productivity and sustainability? To be clear, however, I am not implying that current research programs are unimportant. I am just wondering if we hitting the nail on the head here. What do you think?
    Akwilin Tarimo · Sokoine University of Agriculture (SUA)
    Sub-Saharan agricultural productivity growth has been quite slow despite having a number of international organizations doing research for the purpose of improving the situation. Traditional on-station research has had very little impact on the farming communities although a lot of excellent publications have appeared in international refereed journals. The situation is now improving, however, as researchers revisit their research methodologies in sub-Saharan Africa. On-farm research planning and implementation has greatly brought about change among resource-poor farmers who cannot read publications and their extension workers also have no access to international journals in the rural areas. So with the current change in research methodology and outlook, research in sub-Saharan Africa is reaching the smallholder farmers and will no doubt improve the agricultural situation in the near future.

  • Ian J. Bateman added an answer:
    What is the likely effect on marginal agricultural land use (such as rough grazing) as a result of climate change in a country like the UK?
    Climate change will affect agricultural land use. However it is less clear how individual land use types will change. Within the UK rough grazing land (marginal agricultural land) is important for many ecosystem services. Will it be increasingly converted into more or less intensive use due to the warmer and drier conditions expected for the UK?
    Ian Bateman · University of East Anglia
    Thanks to all who replied to this question - your responses are greatly appreciated and extremely helpful. They will be used to inform ongoing work for the UK National Ecosystem Assessment Follow-On project. Best wishes, Ian
  • Balamurugan L asked a question:
    How to detect the collinear boundary line which is at a specific height ?
    I'm working on automated ground compaction detection and fertilization machine in the agricultural field (particularly peanut cultivation). I want the machine to sense the boundary (end walls of the farmland) of the agricultural field (which is about 6-8 inches) collinearly nearly same height. The sensing should distinguish the alternate heights of the plants which is not collinear. The ultimate aim is that when the machine reaches the end walls (made of sand piles), it should turn to the next lane for further detection of ground compaction.
  • Grace Iyeghe-Erakpotobor added an answer:
    How do I control high kit mortality of rabbits acclimatizing to new environmental conditions?
    Two years ago we imported exotic rabbits from France to improve rabbit productivity in the country. The rabbits have shown good growth rates but are not reproducing very well. We have high incidence of kit mortality during kindling and after kindling even after post weaning stages. The rabbits were imported from a temperate country to a tropical country. They are receiving Vitamin C to reduce effect of heat stress. Air-conditioning and fans are used on very hot days to also reduce effect of heat.
    Grace Iyeghe-Erakpotobor · National Animal Production Research Institute
    Thank you Jacques for the contributions. We are trying to keep the offsprings for selection but our problem is that the current offsprings all died. The temperature range here is between 34 and 38 degrees celsius.

    Sir, there should be a two way communication between the farmers and the administrators and only ICT can provide a solution. To be more specific crowd-sourced platform is needed with the help of which information can be sent by the farmer in the form of SMS, Email, Phone call, websites. All the data should be collected on a common platform, spatial/non spatial analysis should be done and appropriate action should be taken. ( Ushahidi is one such open source platform with the help of which crowdsource website can be created)
